' CHAMFERING ArrA Amus.

,lApplication fi led March 9, 1926. Serial No. 93,423. i

This invention relates to chamfering ap'f paratus, and more particularly to a chamfering attachment for pipe cutting-off and of ohamfering apparatus that maybe readily adjusted for .worl'zing on various sizes of articles,'and which is adapted to chamfer either the outer or inner edges or both edges of the article, as desired.

Another object is to provide chamfering apparatus having the novel design, construction and combination of parts hereinafter described'and illustratedin the accompanying drawings.

Inthe drawingsz' Figure 1 is'afront elevation of'apart of a pipe cutting-off machine having my 1nvention applied thereto.

Figure 21s a sectional plan on the line p 1 1 to lock the toolsor tool and filler block in IIII of Figure 1. y I

Figure 3 is aside elevation thereof looking from the right of Figure 1.

Figure 4 is a side elevation thereof looking from the left of Figu'rel.

Referring more particularly to the drawings, the letter A designates the housing of a standard pipe cutting-off machine, in

which' the pipe Bis mounted the usual-manner. a c

'A" pair of mounting plates 2 are prefer ably mounted one on each side of thewin dow 3 in the'housingand provided'with a plurality of vertically alined threadedholes 4; I,

Bearings 5 and 5 are removably mounted on the plates 2 by bolts or cap-screws 6 and rotated in V which are threaded'into' selected ones of the: holes 4, and thevertical position of thebear- I ings maybe readily'adjusted by removing the bolts or screws '6 and screwing them into other selected holes4; I

A horizontal shaft '7' is journaled in the bearings 5 and 5? and extends beyond the bearing 5 to form a mounting for a hand operating lever 8 which is keyed to the shaft. I

A tool holder 9 having a rectangular slot or opening 10 therethrough is secured to the provided with an attaching flange 15- adapted to overlie the end portions of the outer or rearface of the holder 9.

' The flange 15 of the block 14 is provided with elongated slots 16 to permit shouldered attaching screws or studs16 to pass and be holder 9. i

The toolblock'14 is adapted to be adjustably held against longitudinal movement in threaded into suitable threaded holes in the theopening 10 by set screws 17 threadedin theend walls of the toolholder '9 and The tool block 14 is provided 'with a rectangular slot or recess 18 in which a pair p of chamferingtools for chamferingthe in-x ner and outer edges of a pipe may be mounted, or one tool 19' anda filler be mounted, as shown."

block 20 may pair of set-screws 21 and 2 2 are the opening 18,- and apair of set-screws 28'and 2 4-are threaded in the rear wall of the block 14 and adapted. to adjust the rear i position ofthe tools in the slot or recess 18.

A slot 25 is formed in the side of the tool holder 9 to permit the movement of'the set A coil spring 29 is mounted on the shaft 7 and has one end secured to bearing 5-and the other end secured to the'tool holder 9 and is-adapted to have sufficient tension to normally hold the tool holder 9 in an elevated position away from the pipe or work-piece.

; V In operatiomxthe tool or tools will be ad horizontally by means of the set-screws 23' and 24. After thetool or tools are properly set and the machine is in operation to rotate the pipe or other tubular article, theoperator will pull downon the hand-lever 8; thereby rocking the shaft 7 against the tension of the spring '29 and moving the tool holder 9 and chamfering tool or tools toward the pipe. By exerting pressure on the hand-leverS the operator will force the tool or tools into the ited thereto, since various modifications may be made Without departing from the scope of my invention as defined in the appended claims.

I claim:

1. The combination with a machine for working tubular articles including a housing, of means for chamfering the end of said articles, said means comprising a pair of bearings removably secured to the housing of sa'id machine and adapted to be secured at a plurality of adjusted vertical positions on said housing, a horizontal shaft journaled in said bearings, a tool holder mounted on said shaft and movable therewith, a tool block removably mounted in said holder, chamfering tools mounted in said block, and means for operating said shaft to move said tool vholder into position to cause said tools to engage the article to be chamfered. 2. The combination with a machine for working tubular articles including a housing, of means for chamfering the end of said articles, said means comprising a pair of bearings removably secured to the housing of said machine and adapted to be secured at apluralityof adjusted vertical positions on said housing, a horizontal shaft journaled in said bearings, a tool holder mounted on said shaft and movable therewith, a tool block removably and adjustably mounted in said tool holder, chamfering tools removably and adjustably mounted in said block, and means for operating said shaft to move said tool holder into position to cause i said tools to engage the article to be chamfered. v

3. The combination with a machine for working tubular articles such as pipe cutting and threading machines, including a housing, of means for chamfering the end of the article, said means comprising a pair of bearings mounted on the housing of said ma holder, and a hand-lever secured to said shaft and adapted to be operated to rotate said shaft againstthe tension of said spring to move said tool holder into position to cause said tools to engage the article being worked. r

4. The combination with a machine for working tubular articles such as pipe cutting and threading machines, including a housing, of means for chamfering the end of the article, said means comprising a pair of bearings mounted on the housing of saidmachine, a horizontal shaft journaled in said bearings, a tool holder fixedly mounted on said shaft and movable therewith, a spring mounted on said shaft and having one end secured to one of said bearings and the other end secured to said tool holder,jsaid spring being adapted to normally hold said tool holder in a substantially horizontal or raised position away from the article being worked, chamfering tools mounted in said tool holder, a hand-lever secured to said shaftand adapted to be operated; to rotate said shaft against the tension of said spring to move said tool holder into position to said shaft and movable therewith, a'spring mounted on said shaft and having one end secured to one of said bearings and the other end secured to said tool holder, said spring being adapted to normally hold said tool holder in a substantially horizontal or raised position away from the article being worked, a tool block removably and adjustably mounted in said tool holder, at least one chamfering tool removably and adjustably mounted in said block, and a hand-lever secured to said shaft and adapted to be operated to rotate said shaft against the tension of said spring to move said tool holder into position to cause said tool to engage the article being worked. v i
